6 Claims.

This invention relates to kitchen cabinets which include a base member and a sink overlying the base member, the sink having av horizontally disposed top and an integral -upstanding back. In this type of device the upstanding back, where it joins the horizontal portion of the sink, sometimes is formed as a curve and when the sink cabinet is supported against a vertical wall with the vertical back of the sink likewise backed against this same vertical wall, a Void or space at the ends of the sink is left, which is very unsightly.

Among the objects of the present invention, therefore, is to provide a sink construction, and more specifically a fitting which may be utilized not only to fill this void, but also to secure the sink proper to the upper portion of the cabinet or sink base. f

Other and further objects of the invention will be apparent from a perusal of vthe following specification when taken in connection with th accompanying drawing, wherein: Y

Figure 1 represents a side View of a typical layout showing the cabinet and the sink backed against a vertical wall and with the ller or attachment in position;

Figure 2 is an enlarged perspective view, partly broken away, showing the details of construction;

Figure 3 is a sectional view taken on the line 3 3 of Figure 2; and

Figure 4 is a perspective view of the attachment itself.

Referring now to the drawings in detail, any type of preferably square cabinet 2 is provided to back up against a vertical wall v1I. The .ca-binet is adapted to receive at its top a sink of porcelain or metal of any desired construction. The sink comprises a horizontal top 6 and an upstanding upright back 8 which is generally at right angles thereto and backs also against the vertical wall 4. By reference to Figure 2, these sinks are generally made with the lateral portions thereof bent at right angles as at I and I2 and the free edges of these flanged right angle portions I U and I2 are again bent at right angles as at I4 and I6 to provide a ilange. As heretofore mentioned, it is quite frequently the custom in the manufacture of these sinks to have them curved at their juncture as at I8, and this curve is imparted not only to the top portions 6 and 8 but also the laterally extended flange portions IIJ and I2, and also to the anged free edges I4 and I6, as shown in Figure 2. The cabinet 2 is generally formed with a vertical side Wall I 9 and 2 a fear wall 22, see Figure 3. The side wall I9 is generally arranged flush with the laterally extending flange portions I0 and I2 and the rear Wall 26 is generally extended flush and in the same plane with the vertically extending flange I4. By reference to Figure 3 it will be seen that that portion 20 of the free edge of the laterally turned walls I0 and I2 is disposed on a curve such as 2l which departs from the horizontal top wall 22 of the cabinet base and the vertical wall portion 24 of the end wall of the sink whereby if not taken care of, an unsightly void or space would be left between the top rear wall 22 of the cabinet, the vertical wall 4 and the curved wall 2I of the sink.

The top wall of the cabinet is provided with an inwardly extending flange 26 which lies in a horizontal plane, and the rear wall 20 is provided with an inwardly extending ange 28 lying in the plane of the flange 26. A gusset plate 3B, shown in dotted linesin Figure 2, of triangular shape, overlies and is welded as at 32 and 34 to the ilanges 26 and 28.

Means is provided in the form of an attachment not only for securing and holding the sink rigidly to the cabinet top at both rear sides or corners, but also for filling in the space between the void hereinbefore described. Such an attachment is shown in Figure 4, and comprises preferably a plate-like` portion 36 having an opening 38 for the attaching bolt 40 by which the attachment is secured rigidly to the gusset and hence to the flanges 26 and 28 of the rear portion of the cabinet. This plate is provided with a generally triangularly disposed body portion 42 which at itsfront is formed with angularly disposed walls-V 44 and 46, preferably at right angles. The wall 44, when this attachment is in place, will lie flush with the vertical wall 4 of the sink and the wall 46 will overlie the top wall 22 of the cabinet. The portion 42 is formed with a generally flat face 48 which lies in the same plane as the side 2li of the base of the cabinet and also with the lateral walls I0 and I2 of the sink, whereby to completely and ornamentally lill this corner. The hypotenusal edge 50 between the walls 44 and 46 of the fitting is formed on a gentle curve to accommodate the curve I8 of the sink and to this end the curved portion of the body 42 is formed as a relatively broad curved seat 52 which extends laterally toward the plate portion 36 where it is provided with an overhanging curved wall 54 forming a curved groove 56, which curved groove is adapted to receive the curved flange I'4 of the sink, as shown in Figure 3, and thereby forms an interlocking means to hold the sink rigidly to the base at the rear portions of the cabinet, and by the same token, the portion 48 forms an ornamental filling member for the void, as hereinbefore set forth.

Obviously the invention is not limited to the particular details of construction shown, but is capable of other modications and changes without departing from the spirit and scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. A filler and attachment xture yfor attaching the rear curved corner of a sink having a flange formed thereon to a sink base, comprising al sink corner, and said body having means -for attachment to the sink base at a corner thereof.

2. A rigid tting for a sink having a curved bottom corner wall with a free curved flange formed thereon, comprising a plate having means for attachment tothe upper corner of a cabinet, said plate having an integral body vportion formed at right angles thereto, said `body having side Iedges angularly disposed providing two sides of a generally triangularly shaped face, the third side of which face is curved to join said iirst -two sides,

said curved rside forming a curved seat disposed generally at right angles to said front face to receive lthe curved corner of the sink, and said curved seat being formed with an overlying spaced wall forming a groove to receive the free curved flange of the curved bottomxcorner wall of said sink.

3. In combination with a rigid sink base, an integral, rigid sink having -a one piece, conti-nuous, rigid, horizontal top upright back and rigid, continuous and integral junction walls vwhich are curvilinear, and a fitti-ng positioned below said sink in abutting relation thereto and rigidly interconnecting the sink and base, said fitti-ng `having a wall closing the space between the curvilinear wall of the sink and the rear top of `the base and the lower bottom of the upright wall.

4. In combination with a base for a sink, a sink having a top and an upright back integral and continuous with said top, the integral junctional Walls of said top and back being curvilinear, the rear upright walls of said sink back lying in the plane of the rear upright walls of said base, and a fitting positioned below said sink in abutting relation thereto ,and rigidly interconnecting the 'free-edges of 'the junctional, curvilinear walls of said sink to said base and lling the gap formed ibetween said base and said curved walls.

5. In combination, a base having upper corner walls providing a horizontal support, a sink havng a horizontal bottom and a rear vertical wall, saidbottom sink wall and vertical sink wall being continuously interconnected by a curved junctional -wall forming a lower rear curved corner for the sink, and said sink backing against a vertical wall, and a fitting having a portion fixed to said base and having a curved outer wall flush with `the outer end Walls of the base and sink and hai/:ing an inwardly disposed curved groove, said sinkatqsaid rear curved corner having a laterally inwardly extending, curved nange interlocking in the .grooveof ysaid fitting, and said outer wall t ting the space between :said base, said sink, and said last mentioned vertical wall.
